FIG. 1 is a schematic structural diagram showing an innovative leather according to an embodiment of the present disclosure. In an embodiment, the leather 10 of the present disclosure includes a Polyester substrate 11, a Polyester adhering layer 12 and a Polyester surface layer 13.

In an embodiment, the Polyester substrate 11 has a first surface 111 and a second surface 112. The second surface 112 is opposite to the first surface 111. The Polyester substrate 11 is made of a PET (Polyethylene Terephthalate) material, which is an engineering plastic. The Polyester substrate 11 may be a non-woven fabric formed by bonding 100% PET recycled cotton or a mixture of 60% PET recycled cotton and 40% PET cotton by needle punching; or a woven fabric formed by weaving 100% recycled PET fibers or common PET fibers. Therefore, the Polyester substrate 11 is completely made of the Polyester material. In an embodiment, the Polyester substrate 11 may be made of a TPEE (Thermoplastic Polyether Elastomer) material or a PBT (Polybutylene Terephthalate) material.

In an embodiment, the Polyester adhering layer 12 is disposed on the first surface 111 of the Polyester substrate 11. The Polyester adhering layer 12 may be made of a TPEE (Thermoplastic Polyether Elastomer) material, which is an engineering plastic having properties of an elastomer; or a PBT (Polybutylene Terephthalate) material, which is a thermoplastic engineering polymer. The Polyester adhering layer 12 has a weight of 50-400 g/m² and a density of 0.2-0.8 g/cm³. The Polyester adhering layer 12 is thermoplastic, in an embodiment, the Polyester adhering layer 12 may be made of a PET material.

In an embodiment, the Polyester surface layer 13 is disposed on the Polyester adhering layer 12. The Polyester surface layer 13 may be made of a PET, TPEE or PBT material. The Polyester surface layer 13 has a weight of 50-400 g/m² and a density of 0.5-0.9 g/cm³. The Polyester surface layer 13 is thermoplastic.

In an embodiment, the leather 10 of the present disclosure includes the Polyester substrate 11, the Polyester adhering layer 12 and the Polyester surface layer 13. The Polyester substrate 11, the Polyester adhering layer 12 and the Polyester surface layer 13 are made of a single Polyester material without other materials. Therefore, all materials of the leather 10 of the present disclosure are the same Polyester materials, thus the leather 10 of the present disclosure can be recycled and granulated after the leather of the present disclosure is used. The leather of the present disclosure has environmental benefit. Moreover, thermoplastic Polyester recycled particles obtained after recycling and granulation may be added to the manufacturing process of the leather 10 of the present disclosure to further enhance the recycling benefit, thereby saving the manufacturing cost.

In an embodiment, Since the leather 10 of the present disclosure is made of the single Polyester material which has higher glass transition temperature and melting point, when the leather 10 of the present disclosure is applied to a product, the product may have higher temperature resistance and thermal stability. Moreover, since the Polyester material has more excellent mechanical strength, when the leather 10 of the present disclosure is applied to a product, the mechanical strength of the product may be increased. For example, when the leather of the present disclosure is applied to a shoe material, the tensile strength and the tear strength may be increased, so the usability of the product may be enhanced. Furthermore, since the Polyester material has lower density, when the leather 10 of the present disclosure is applied to a product, the overall weight of the product may be decreased, which makes the product lighter and more suitable to wear for a long time.

In an embodiment, as described above, the thermoplastic Polyester recycled particles obtained after recycling and granulation may be added to the manufacturing process of the leather 10 of the present disclosure. The Polyester surface layer 13 includes a thermoplastic Polyester material and a thermoplastic Polyester recycled material. The thermoplastic Polyester material and the thermoplastic Polyester recycled material are mixed in a weight ratio of 75%:25% to 100%:0%.

FIG. 2 shows a flowchart of a manufacturing method of an innovative leather according to an embodiment of the present disclosure. With reference to FIG. 1 and FIG. 2 , referring to step S21 first, a Polyester substrate 11 is provided. The Polyester substrate 11 has a first surface 111 and a second surface 112. The second surface 112 is opposite to the first surface 111. In an embodiment, the Polyester substrate 11 is made of a PET (Polyethylene Terephthalates) material. The Polyester substrate 11 may be a non-woven fabric formed by bonding 100% PET recycled cotton or a mixture of 60% PET recycled cotton and 40% PET cotton by needle punching; or a woven fabric formed by weaving 100% recycled PET fibers or common PET fibers. Therefore, the Polyester substrate 11 is completely made of the Polyester material.

Referring to step S22, a Polyester adhering layer 12 is melt-blown onto the first surface 111 of the Polyester substrate 11. In an embodiment, the step of melt-blowing the Polyester adhering layer 12 further includes using first thermoplastic Polyester particles (not shown) having a melting point of 120-150° C. The first thermoplastic Polyester particles may be PBT particles or TPEE particles. In an embodiment, in the step of melt-blowing the Polyester adhering layer 12, a melt-blowing distance is 250-350 mm.

Referring to step S23, a Polyester surface layer 13 is melt-blown onto the Polyester adhering layer 12. In an embodiment, the step of melt-blowing the Polyester surface layer 13 further includes using second thermoplastic Polyester particles (not shown) having a melting point of 130-170° C. The second thermoplastic Polyester particles may be TPEE particles. In an embodiment, in the step of melt-blowing the Polyester surface layer 13, a melt-blowing distance is 150-250 mm.

In an embodiment, the step of melt-blowing the Polyester surface layer further includes using thermoplastic Polyester recycled particles. The second thermoplastic Polyester particles and the thermoplastic Polyester recycled particles are mixed in a weight ratio of 75%:25% to 100%:0%. The thermoplastic Polyester recycled particles may be thermoplastic Polyester recycled particles obtained by recycling and granulating the leather of the present disclosure after use.

Referring to step S24, the Polyester substrate 11, the Polyester adhering layer 12 and the Polyester surface layer 13 are thermally compressing and bonding. In an embodiment, in the thermally compressing and bonding step, a temperature is 140° C.-160° C. In the thermally compressing and bonding step, since the temperature is higher than the melting point of the first thermoplastic Polyester particles, the Polyester adhering layer 12 may be melted and then bonded with the Polyester substrate 11 and the Polyester surface layer 13.

In an embodiment, after the thermally compressing and bonding step, the leather of the present disclosure may be subjected to surface thermoplastic processing, such as a thermoplastic embossing process, such that the leather of the present disclosure has different surface textures.

Therefore, according to the manufacturing method of the leather of the present disclosure, the Polyester substrate 11, the Polyester adhering layer 12 and the Polyester surface layer 13 are made of the single Polyester material, and thus prepared from the single raw material, so the process and material preparation of the manufacturing method of the leather of the present disclosure are simplified, which can enhance the manufacturing efficiency and lower the manufacturing cost. In addition, the leather 10 of the present disclosure can be recycled and granulated after being used. The leather of the present disclosure has environmental benefit. Moreover, thermoplastic Polyester recycled particles obtained after recycling and granulation may be added to the manufacturing process of the leather 10 of the present disclosure to further enhance the recycling benefit, thereby saving the manufacturing cost.
